apologies I see that I have the descriptions wrong way around. im not too sure exactly how much this will save but if those automakers are adding such small ones im sure it makes a difference. as for the construction of the flaps the wood you can see in the images are balsa wood used in rc plane construction. its easy to shape and mould. once I have a mould the items are going to be made from carbon fibre. I happen to have a younger brother working with this stuff daily. these are some aero pieces he made for his car to cover a channel running along his pillars. he also has a full carbon fibre engine under tray. he will be making my parts too







undertray a bit dirty but it is made of high density foam sandwiched between 2 layers of carbon fibre
